The #59M™ S.I.R.® system is the perfect free floating handguard rail system to add to your rifle to upgrade it to a sniper-capable precision rifle platform. Mounting directly to your flat-top receiver provides a rigid optics mounting rail, raises the platform high enough to use medium height rings, and is strong enough to withstand the hardest military use. The polymer lower handguard stays cool during extended range sessions and the forward aluminum lower handguard is railed to provide a stable mounting platform for bipods.
As with all of our S.I.R. systems, selective rails can be added at various locations along the sides and bottom of the system or removed if required. The #59™M includes short #1 and #2 selective rails and a sling swivel that can mount directly to the S.I.R. in any of the threaded holes on the accessory rails or the lower handguard.
The rear of the S.I.R. is contoured to allow mounting any of our #40 series flip-up rear sights.
